Speed control of motor using SCR?
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
Future scope of dc motor speed control using rf?
The DC motor speed control has a scope of four speeds. The control speeds include; high, medium, low, and off.
How does bridge rectifier control a DC motor?
give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
Speed control of three phase induction motor by supply voltage control using AC voltage regulators?
No. Use standard utility AC, 3 PH voltage to feed a Variable Frequency Drive (VFD). The VFD is then wired to the motor. The output of the VFD varies average voltage and frequency in a semi-constant proportion to keep Volts/Hertz ratio the same to the motor. The operator can then adjust or select the desired speed from the VFD and the VFD will run the motor continuosly at that desired speed. If you were to control only voltage to the motor without adjusting frequency in proportion, the motor would burn up.
What is the maximum current of the pole changing motor when running at low speed and high speed?
The maximum current of the pole changing motor when running at low speed and high speed depends on a few different things. The average when begin at low speed and using high speed is 1800 RPM points.

How do you introduce feedback circuit in dc motor speed control?
By using your brain
How do you control speed of AC servo motor?
well, you either have to program the operating frequency crystal to a better remote control, (if you are using a remote control,get remote control which can control the speed) or, try using a more powerful or less powerful battery to increase or decrease the speed.
Can a rheostat be used to control speed on a capacitor run motor?
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
How thyristor control the motor speed?
Thyristors control motor speed by regulating the voltage applied to the motor, which in turn affects its speed. By using phase control techniques, thyristors can adjust the point in the AC cycle at which they are triggered, effectively reducing the average voltage supplied to the motor. This results in a decrease in power and speed. Additionally, thyristors can be employed in various configurations, such as inverters or chopper circuits, further enabling precise speed control in different types of motors.
Speed control of a.c motor?
Use a variable Frequency Drive. Sold by ABB, Allen-Bradley, and many others.
What is ac drive and how it works?
An AC Drive used for a speed control of a motor by using vary frequency.
What are the advantages of speed control of DC motor using micro-controller when compared to other?
This motor is able to work from the battery. The speed is less complicated to use and you do not need much voltage.
How do you reduce the speed of a 15 kW 3 phase motor without using variable speed control?
If the load is connected to the motor via belts, you can change the speed the load is turning by changing the pulley sizes. To get the load to slow down, increase the size of the pulley on the load; to get it to speed up, increase the size of the pulley on the motor. To reduce the speed of the motor itself, you'll have to alter the line frequency, which you can't do without a variable frequency drive attached to the motor.
How motor can control using timer contactor?
Control means, a timer cant control is speed directly, it can control its operation. A times will have NO nd NC contacts. Connect the motor in series with the timer contacts wrt desired operation
How control dc motor using micro controller?
The speed of the motor depends on load, voltage and current. The speed can be maintain by using a method called Pulse code modulation (PWM). By changing (modulating) the width of the pulse applied to the DC motor we can increase or decrease the amount of power provided to the motor, there by increasing or decreasing the motor speed. mean we have to just change the duty cycle of modulating output.
